PUMP LINER Filed Jan. 19 1927 I N V EN TORS.
mR/s THOMAS By MART/N L. K/NNEY A TTORNE Patented Oct. 8, 1929 UNITED STATES PATENT OFFICE IDRIS THOMAS, OF WHITTIER, AND MARTIN L. KINNEY, F BELL, CALIFORNIA PUMP LINER Application filed January 19, 1927. Serial No. 162,032.
placeable in a usual cylinder structure which may include a usual shell of cast-iron or the like mounted in a pump in accordance with the present liner practice.
It is a further object of the invention to provide an arrangement wherein all of the wearing action is at the steel liner so that the cylinder structure may remain in constant use with replacement of only the liner necesreception of a packing ring 8 between shell sary in order to renew the cylinder.
It is a still further object of the invention to provide retaining means for the replaceable steel liner which permits it being readily osition for use; and which also provides or its quick and positive withdrawal, irrespective of any tendency to stick, when such replacement be comes necessary as a result of wear.
It is a still further object of the invention to provide for packing-off between the liner proper and the cylinder structure; and to tighten the packing means at the same time a that the liner is fixed in operativeposition.
Further objects of the invention will be readily understood from the following description of the accompanying drawings, in which: I Fig. 1 is a side elevation of the liner, partly in axial section, showing it in operative position.
Fig. 2 is a transverse section on the line 22 of Fig. 1. c
. Fig. 3 is a view similar to ing a modified construction.
The liner is adapted. for use in a usual pump or the like which is indicated at A and 1 but showwhich is provided with a usual head B. Theliner 1 is of steel or other suitable wear reas shown at 3 to form an abutment for packing (not shown) which is adapted to be placed between the shell 2 and the bore of pump A, with a flange 4 at the end of the shell adapted for abutment against the end ofthe pump in order to properly POSltlQP the shell.
The inner end of the bore of shell 2 has an interior flange 5 forming a seat for the inner end of liner 1; and a packing ring 6 is preferably mounted between the cooperating seat and liner end, with said cooperating surfaces inclined as shown at 7. The outer end of the bore of shell 2 is preferably counter-sunk for 2 and liner 1; and the outer end of the liner which projects beyond the shell is threaded as shown at 9 to receive a flange 10 which abuts against packing 8 and the flanged outer end of the shell.
The steel liner is fixed in its shell by detachable means shown as bolts 12 received through openings 13 in flange 10 and adapted for threaded engagement in tapped bores 14: in the flanged outer end of shell 2; and by this arrangement flange 10 may be threaded onto liner 1 to the desired adjustment, and connected to the flanged outer end of shell 2 by tightening bolts 12, thereby compressing packing 6 and 8 to form a fluid-tight connection between the liner and its shell and posibolts C which are threaded through the head and adapted to engage flange 10 so that flange 4 abuts against the end of the pump.
The" steel liner being subject to allthe wearing action, it is the only part which need be replaced when renewing the pump cylinder; and for the purpose of such replacement the head B is removed in usual manner 2 so as to release bolts C, and the bolts 12 are withdrawn so that the steel liner is no longer positively fixed relative to its shell. Liner 1 is then readily withdrawn and replacedwithout disturbing shell 2, any tendency of the steel liner to stick being overcome by a positive operating engagement.
As an instance of this arrangement the flange 10 may be tapped as shown at 16 for l0 and the steel liner which is connected thereto, by screwing-up the bolts so as to increase their pressure against the shell.
The invention contemplates interchangeable use of wear-resisting liners of diilerent diameter, the modification of the invention shown in Fig. 3 illustrating the use of a replaceable liner 1 which is of smaller diameter than the bore of the cylinder structure. For this purpose an annulus 20 is mounted in the cylinder structure and is shown as seating at 21 on the flange 5 of shell 2, and the bore of the annulus forms a flange 5 adapted to seat the inner end of liner 1 by means of cooperating inclined surfaces 7 as previously described. An annulus 22 preferably seats in the counter-sunk outer end of shell 2 and is adapted to receive the outer end of the reduced liner 1*, and the annulus 22 may be counter-sunk for reception of packing 8 as previously described. The flange 10 is of I the proper internalv diameter to engage the replaceable liner and overlie the annulus 22 and the flanged end of shell 2; and the parts are fixed relative to one another, with liner l adapted for positive withdrawal, as previously described.
We have thus provided extremely simple and inexpensive means for replacing wearresisting liners in a cylinder structure, the construction permitting use of liners of dif- :ferent diameter and positively fixing the liner in place by a fluid-tight connection, with means provided for positively withdrawing the replaceable liner should it tend to stick, and the arrangement also particularly adapting the replaceable liner for mounting in a usual removable shell, although it will be obvious that the liner may also be employed in various other cylinder structures.
